can you please criticise my work?

[plasticsurgery13]

I'm an aspiring artist and i need ome criticism....
im getting a little tired of constantly hearing from my peers that eveything i do is good,or great,or whatever....
the positive feedback is nice but i dont want to get too comfortable and not acheive my full potential....
so if you guys wouldnt mind,would you look at my my most recent works and tell me how they look....
if they're good,bad,crappy....
i dont care...
i need the criticism and it would be VERY apprechiated:]
im sorry if it seems like there's alot...
i just do some diverse work smile

With Much Love And Respect,

p.s. for anybodywondering,no i did NOT go to any type of art school...
the ONLY type of art class i had was in elementary school and it was basically an outlet of expression,no specific way of drawing things.

(if there's any questions about any of these feel free to ask any questions biggrin )
here are the links:
